HEATING SYSTEM FOR EXPLOSION-ENGINES.

Specification of Letters Patent.

Application filed December 8, 1910. Serial No. 596,209.

To all whom it may concern:

Be it known that I, STANISLAW J. LUKAB znwsKI, a citizen of the United States, and

a resident of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Heating System for Explosion- Engines, of which the following is a specification.

This invention relates to means for preventing the chilling or freezing of the circulating water or other liquid of automobileengines and other explosion motors which are exposed to extreme changes of tempera- -ture, and its object is to connect a heating device into the circulating system, whereby the motor may be kept warm.

This invention consists in a heating coil connected to the radiator and to the engine, together with a burner to heat the liquid in the coil, the parts being so arranged and proportioned that the heated liquid will circulate through the engine and through the radiator.

In the accompanying drawing, Figure l is a plan of the front part of an automobile frame with the hood removed. Fig. 2 is a vertical section of the heater. Fig. 3 is a plan of one coil on the line 33 of Fig. 2. Fig. 4 is a detail of the regulating valve.

Similar reference characters refer to like parts throughout the several views.

Motors of automobiles are hard to start after they have stood out in the cold for some time becausethe walls of the cylinders become chilled. A common practice is to blanket the hood and radiator to retard the escape of heat, but this only partially mitigates the evil, for in a short time, the liquid in the radiator becomes chilled. As the liquid is usually in constant circulation, the engine too gets very cold, resulting in the lubricating oils getting stiff and also affecting the explosion. As a result, it is often cylinders; 7 is the, engine shaft; 8 is the "fly-wheel; 9 is the radiator of the engine and 29 is the dash board of the automobile.

Between the radiator and the engine are the circulating pipes 10, and 11, the former leading from the sides of the water jackets of the cylinders, and the latter leading from the top of the cylinders to the top of the radiator. The circulating liquid flows through the pipe 10 from the radiator to the engine, and through the pipe 11 from the engine to the radiator at all times, resulting in the cooling of the engine, excepting in such engines which are equipped with a circulating pump, in which cases, the liquid does not At any convenient place within the hood,

and preferably connecting the bottom of the radiator by means of a separate pipe 12 and to the circulating pipe 10 near the engine by a pipe 19, is a heating device, which may be of any desired construction. That shown consists in a set of coils of pipes 13, a shell 14, heads 15, and a burner 16. While a kerosene lamp might be employed, a gasolene burner is preferred. The. fuel feed pipe 17' connects to the gasolene tank or to the fuel pipe of the engine, source of supply. The burner shown is of the well-known ring type having a small pilot burner 18. When an excess of gasolene flows through the pipe 17, the pilot light will be merged in the general blaze, but

when the supply is limited, a small flame will be located at the central orifice.

While any desired means may be employed to control the flow of fuel oil, I prefer to employ a device at the dash-board which may be the crank or button which controls the spark; At one end ofthe shaft 20 is a crank handle 21, and at the other, the crank 22 which connects to the crank 23 on the stem 24 of the needle valve 25 by means of a link 28. By turning the crank handle 21 the valve stem 24 will be turned in or out, moving the needle valve 25 toward or from its seat 2.6 in the body 27, and thus controlling the flow of the fuel oil.

the bottom of the radiator to or to any other a what I claim as my invention and desire to secure by Letters Patent is 1. The combination with the cylinders and radiator of an explosion engine, of pipes between the same to convey the circulating liquid, and a heater comprising a coil and I a burner, one end of said coil connected into one of the pipes, the other end connecting to the radiator, said heater adapted to prevent the circulating liquid from chilling.

2. The combination with an explosion engine, of a radiator for cooling the circulating liquid thereof, of pipes for conveying the liquid from the engine to the radiator and from the radiator to the engine, of a heating coil connected into one of said pipes and to a liquid supply, a burner beneath said coil, and means for controlling .said burner.

3. The combination with an explosion engine, of a radiator for cooling the circulating liquid thereof, of a pipe system for conveying the liquid between the engine and radiator, of a heating coil connected at one end into said pipe system and at the other end to 'a liquid supply, a burner beneath said coil comprising a main burner and a pilot light, a pipe for conveying fuel oil to the burner, a valve in said pipe, and means for positioning said valve to vary the fiow of the fuel oil between amounts necessary for the pilot light and for the main burner.

In-testimony whereof I have signed this specification in the presence of two subscribing witnesses.
